CARD-WASTE TRANSMITTER. A

SPECIFICATION forming part of Letters Patent No. 508,488, dated November 14, 1893.

' Application filed August 11, 1893- Serial No.432,929. (No model.)

To (ZZZ whom it may concern.-

Be it known that we, ROBERT E. ROBINSON and EDWARD P. CONLEY, citizens of the Dominion of Canada, residing at Sherbrooke, in

the county of Sherbrooke and Province of Quebec, Canada, have invented certain new and useful Improvements in Gard-Waste Transmitters; and we do hereby declare the following to be a full, clear, and exact dero scription of the invention, such as will enable others skilled in the 'art to which it appertalns to make and use the same, reference being had to the accompanying drawings, and to figures of reference marked thereon, which I 5 form a part of this specification.

This in'vention'relates to pneumatic card waste transmitters such as are adapted to work back waste side ends from finisher cards;

Our invention relates to a system, which consists of a single blast pan serving to deliver air into a main pipe extending beneath the card-roomfioor. From said" main pipe, branch or transmitting pipes are supplied for each side end; two for each finisher-card.

Rising from said branch pipes is a small tube, which serves to conduct and acts as a feed to lead the side-end into the branch pipe; it being understood that the side-end is 0 first drawn down said tube and subsequently blown back to the first or second breaker card as is desired.

Our invention consists in an arrangement of co-operati'ng elements by which no posi- 3'5 tive mechanical agencies are employed to seize the side-end in order to cause the latter to enter the transmitter, and further in instrumentalities by which back draft in the supply tubes is avoided; likewise inthe po- 4 culiar construction of the delivery end of the transmitter pipes whereby the side-end is passed to the breaker and transferred without the aid of direct mechanical agencies.

The drawings represent in Figure a side elevationof a pneumatic card-waste transmitter embodying our invention. Fig. 2 is a sectional view enlarged of the delivery end of the transmitting pipe. Fig. 3 is a sectional view enlarged-of the delivery tube and transmitter pipe at the point wherethe sideend enters the latter. Fig. 4 is a diagram of our invention as applied.

In the accompanying drawings 2 represents the floor of a card-room in which are located finisher cards, one of which is illus- 5 5 trated at 3 with condensing rolls at 4, where the side-end 5 is formed. At any suitable place is located a blast pan 6 and connected therewith is a main air pipe 7, which is preferably beneath the floor of the card-room. In fact the entire system is to be below the .fioor with the exception of the tubes 8. These latter extend up through said floor and terminate at a point in proximity to where the side-ends are formed; said feed tubes serving 6: to convey the-side-ends to the transmitting pipe. These feed tubes are surmounted with porcelain mouth-pieces 20 or other-insulating material to prevent the side-ends from sticking thereto because of electrical attraction.

As will be seen by reference to Fig. Leach finisher card is supplied with branch ortransmitting pipes 9, which extend from the main vpipe 7 laterally of each finisher card, one for either side, and said pipes terminate at the first or second breaker card as is desired. The supply tubes 8 are shown removably mounted in the transmitting pipes, while a gate 10 is positioned in said pipe at a point in advance of that where the side-end enters the transmitting pipes. Thediameter of themain pipe is to be of such capacity as will more than supply all the transmitter pipes. Hence air enters the latter under slight pressure. To prevent such air under pressure of the fan from entering the vertical supply tube 8 and so cause a back draft, the latter are extended into the bore of the transmitter pipes preferably to the center of the latter. Furthermore the main transmitting portion is enlarged in diameter ata point beyond the point of entrance of the supply tubes. The gate 10 is adj ustably mounted and operated by a rod 12, which extends through the floor 2 of the card-room. 9 5

7 The effect of the above arrangement of elements is such that thepassage of the air transversely across the bottom of the supply tube 8 naturally tends to draw and suck down air after the action of an injector. To increase such action the gate is employed to reduce the bore of the branch pipe before it reaches the extremity of the supply tube; thence the air passes by with increased velocity, while after such air has performed this duty and entered the enlarged portion it is not sufficient in volume to fill such portion. Consequently more air rushes down the supply tube to make up the deficiency. In this manner, no mechanical agencies are required to grasp the sideeud, but the latter is drawn and sucked down the tube 8 and thence conveyed in an unbroken condition to the breaker card. The discharge of said waste ends into the breakers is another important feature in our invention. Necessarily in order to create a suction down the supplytubes 8, the transmitter pipes must have open ends; therefore to allow escape of air and yet compel the side ends to pass upon the periphery of the breaker cylinder 13 perforations or vents 14 are created in the walls of the pipe as shown. Moreover to cause the side-ends to properly engage the card clothing a guide-plate 15 is attached to said pipe and curved to conform to the periphery of the cylinder, while the perforated end portion 16 and the guide-plate are pivotally attached at 17 in order to afford adjustment and enable the deliveryend to be properlypositioned with respect to said cylinder. This vertical portion 18 may be made of two parts to telescope, and thus provide for vertical variation of the breaker cylinder above the floor.

In case the supply tubes should become obstructed for any cause, their clearance is readily obtained by lifting the gate 1011p and allowing the air full vent through the smaller length of the transmitter pipe with the result that the air backs up and escapes upwardly through the supply tubes at the same time forcing out and expelling the material accidentally caught or wedged therein.

What we claim is 1. The combination with a series of carding engines, and groups of condensing rolls therefor, of a single blast fan and a main supply pipe, a series of branch pipes with perforated terminals and composed of two lengths of difi'erent diameters, supply tubes from the condensing rolls to the trasmitter pipes for passage of side ends, and a gate between the main pipe and the delivery end of the supply tubes all operating substantially as explained.

2. The combination with a finishing card, its condensing rolls, and supply tubes for passage of side ends, of a main pipe for air blast, a breaker, transmitting or branch pipes from said main pipe to the breaker, pivotal perforated extremities for said transmitting pipes, said pipes being contracted at or near the main air pipe and receiving the lower extremities of the supply tubes, and a gate mounted in said transmitting pipes, substantially as described.

3. The combination with asingle blast fan, and amain pipe therefrom, of aseriesof transmitting pipes composed of two portions, an enlarged terminal portion provided with a pivotal extremity with wall perforations, a contracted portion united to the main supply pipe, a supply tube affixed to said contracted part and projecting within the bore of the latter, and a gate between the extremity of the supply tube and the main pipe, substantially as described.

4. The combination with a finishing card, and its condensing rolls, of a main pipe for forced air draft, a pair of transmitting pipes from said main pipe composed of a large and a small length, a supply tube, the lower extremity of which extends into said small length, a gate between the said supply tube extremities and the main air pipe, a pivotal terminal with wall perforations mounted on said larger length, a breaker, and a curved guide plate to conform to the periphery of the breaker and direct the side end upon the card clothing, substantially as described.

In testimony whereof we affix on r signatures in presence of two witnesses.
